Used in neuroscience research to quantify N-methyl-D-aspartate receptor (NMDAR) levels in biological samples such as brain tissue, cerebrospinal fluid, or cell lysates. Enables investigation of NMDAR expression changes in neurodegenerative diseases like Alzheimer's, Parkinson's, and Huntington's disease, as well as in psychiatric disorders including schizophrenia and depression. Supports studies on synaptic plasticity, excitotoxicity, and the effects of drug treatments targeting glutamate signaling. The kit provides a reliable, high-throughput method for detecting receptor protein levels, aiding in both basic research and preclinical drug development.
